a small help please

hello guys
in the picture bellow i have an Acapulco gold from barneys farm
vegging for 22 days under a bridgelux vero 29 4000k 80 cri at 2100ma .tend temperature 24-29 Celsius max,water hp 6.8. everything is going ok except the last 2 days.my leaves is starting to losing a bit the green color is that a magnesium deficiency?today i feed her for first time i 'm using miller nutrient express 18-18-18
i use 0.4 gr in 1 lit of water(of course i ddin't use all the water) if it is magnesium def.. should i use calmag solution or it is ok with my miller fertilizer?miller have 0.50% Mg any idea can helpful

Get some cal-mag.

check for mites too

looks as if they are just due to be fed. my babys lose theyre lush green when hungry this resolves after 24 hours after feeding. provided im correct, i may be wrong but it just looks as if its hungry. you will see by tommorow for sure. good luck

thanks for the advises!!!
i'm sure i don't have mites ... tomorrow i will see the results of my feeding.
if the problem still exists i will use a cal mag solution or Epsom salts?in witch solution i will have faster results?

its on its 5th node its time to feed thats it , start at 1/4 strength for 2 feeds then 1/2 . i never feed at full strength for the fear of nute burn , a lot easier to feed more often than to scortch it . start a grow journal would like to watch , good luck .

i have no hps no mh no cfl...as i mention in this post i use a bridgelux vero 29 4000k 80 cri about 82 real wats next week after i trasnplant her i will use an other one at 2700k

u are so gunna need more light man lots lots more i looked em up ;(

• Market leading efficacy of 120 lm/W typical and 110 lm/W minimum
• Vero 29 lumen output performance ranges from 2,500 to as much as
6,000 lumens
• Broad range of CCT options from 2700K to 5000K
• CRI options include minimum 70, 80, and 90
• 2 and 3 SDCM color control for 2700K-4000K CCT
• Reliable operation at up to 2X nominal drive current
• Radial die pattern and improved lumen density
• Thermally isolated solder pads
• Onboard connector port
• Top side part number markings

VeroTM represents a revolutionary advancement in chip on board (COB) light source technology and innovation. These new LED light
sources simplify luminaire design and manufacturing processes, improve light quality, and define a platform for future functionality
integration.

Vero is available in four different LES (light emitting surface) configurations and has been engineered to reliably operate over a
broad current range, enabling new degrees of flexibility in luminaire design optimization. These new arrays deliver increased lumen
density to enable improved beam control and precision lighting with 2 and 3 SDCM color control standard for clean and consiste

80 wats veg state and 160 wats led flowering state is not enough? for one plant in tend 60cm x60 cm x 160cm?there are proves for what you can do 160 watts of vero 29.maybe its better to start my 2700k before i turn it to flowering state
bridgelux 4000k 80 cri 127 l/w
2700k 90 cri 93 l/w( but high cri bigger pick 600-630 nm)
• Vero 29 lumen output performance ranges from 2,500 to as much as
6,000 lumens (i'm running at 2100mA so it's bigger than 6000 lumens )
and something more... yes its true 60000 lumen for 400w hps but 120wats is real light the other just heat. Lumens is not so important for plants there are other characteristics that are more important for them.

it may have the same lumans but what about spectrum and penatration is it gunna do it ?

Ive never heard of that miller stuff. Get some high quality nutes designed for growing dope, Canna ,Dutchfest, advance nutes for eg.
18-18-18 is no good for veg and ph 6.8 is too high it has to be 5.8 .

By the way what are they growing in? looks like straight woodchips.

thanks for the advise
maybe this nutes are not designed for dopes but i can assure you with this nutes people has good results with growing cannabis (there was many proves but the forum is closed...)yes this ferts is not so good for beginners you can burn the plant very easy...that's why is better to use the ferts that mention...the medium that i use is biobiz all mix with 20% more perlite... maybe i didn't watered this spots well and my camera make it more brown

Idk y this buds kid says it looks like straight wood chip but suggests a 5.8 pH that's for hydro ur pH is closer to what u want though 6.5 is optimum for soil but good god 5.8 ph ur plants won't get shit in soil also just bc the nuets this kid uses are not those nuet company that have 15 diff things in a line that could b accomplished with prolly half of that and half the spending does not mean he won't get good results if it works for u man use it and more power to u for not getting sucked in to the greed of big nuet companies not that they don't work just could of got to ur end product with prolly half the stuff and money spent
I do think though that ur plant should come around after u give it a feed just looks hungry good luck man
